Tach Conversion - Mechanical To Electric

[Eddie 70]

Since my oil pressure gauge conversion from mechanical to electric works, I thought I would try and jump to my next project in the conversion. I want to take my stock tach and make it work with the LS conversion. Since my mechanical tach now has no input, we have to give up the mechanical guts and put in some electrics. I have read at some point that someone took the guts out of a 77 or so tach and put them behind the earlier face and made this work.

Does anyone have any idea of who may have done this or how to accomplish this conversion? I don't have a tach yet but I am ready to get on with it. Any help or pointers would be greatly appreciated. I did see it mentioned on one of the forums. The poster said to do a search for the conversion, I did and found 0. I am all ears.

Eddie, here's a site4 that does it for $200.00, so it IS able to be done.

I went to Google and typed in the following including the quotes .......
"tachometer conversion" +corvette
It returned 170+ hits. You can probably copy and paste it.......
Good luck,
